If a 10 ohm resistor is connected to a 30V battery, what is the energy consumed

If a 10 ohm resistor is connected to a 30V battery, what is the energy consumed in 5 seconds?

If a 10 ohm resistor is connected to a 30V battery, what is the energy consumed in 5 seconds?

Step 1: Identify the values given in the problem. We have a resistor of 10 ohms and a battery of 30 volts.
Step 2: Use the formula for power (P) which is P = V^2 / R, where V is voltage and R is resistance.
Step 3: Substitute the values into the formula: P = (30V)^2 / 10 ohms.
Step 4: Calculate (30V)^2, which is 900.
Step 5: Divide 900 by 10 ohms to find the power: 900 / 10 = 90 watts (W).
Step 6: Now, calculate the energy consumed using the formula: Energy = Power * Time.
Step 7: Substitute the power and time into the formula: Energy = 90 W * 5 seconds.
Step 8: Multiply 90 by 5 to find the energy: 90 * 5 = 450 joules (J).
